Benefits to the Perl Community
Powerful console-based utility is useful, but it becomes much more attractive when it has ability to easily create interfaces, so demos and screenshots will be better looking. Given that Tk 8.5 as compared to 8.4 have much more attractive look-n-feel (better screen fonts and native widgets via tile) it will be much benefit for users.

Deliverables
Mostly, this is yet another CPAN module adopted for future version of Perl.

Project Schedule
On average I will spend every day for two hours and will complete the project within 3 weeks.

Biography
I have experience of Perl programming for more than 10 years, I am now the maintainer of Tcl and Tcl::Tk CPAN modules, so have understaiding of interconnecting Perl and Tcl/Tk.

The tcl in /languages is partcl, the Tcl implementation on parrot. I understand Tcl::Tk uses the Oosterhout Tcl implementation as a bridge to access Tk. It's that approach, embeding an external language into parrot, that I find blasphemous. If you could use partcl as a replacement that would be quite cool, but as far as I understand (but I'm not an insider) it is not mature enough yet to support that.
